cURL , get redirect url to a variable
提问by Vamsi Krishna B
I'm using curl to fill a form. After completion of the post the other script which handles the form is redirecting to another URL. I want to get this redirect URL into a variable.
我正在使用 curl 填写表格。帖子完成后，处理表单的另一个脚本将重定向到另一个 URL。我想将此重定向 URL 放入一个变量中。

Easy way to find the redirected url (if you don't want to know in advance)
查找重定向网址的简便方法（如果您不想提前知道）
$last_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

You would use
你会用
curl_setopt($CURL, CURLOPT_HEADER, TRUE);
And parse the headers for the locationheader
并解析标题的location标题

Here I get the resource http headers then I parse the headers out into an array $retVal. I got the code for parsing the headers from here (http://www.bhootnath.in/blog/2010/10/parse-http-headers-in-php/) You could also use http://php.net/manual/en/function.http-parse-headers.phpif you have (PECL pecl_http >= 0.10.0)
在这里，我获取资源 http 标头，然后将标头解析为数组 $retVal。我从这里得到了解析标题的代码（http://www.bhootnath.in/blog/2010/10/parse-http-headers-in-php/）你也可以使用http://php.net/手册/en/function.http-parse-headers.php如果你有 (PECL pecl_http >= 0.10.0)
$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
// Getting binary data
$header = curl_exec($ch);
$retVal = array();
$fields = explode("\r\n", preg_replace('/\x0D\x0A[\x09\x20]+/', ' ', $header));
foreach( $fields as $field ) {
if( preg_match('/([^:]+): (.+)/m', $field, $match) ) {
$match[1] = preg_replace('/(?<=^|[\x09\x20\x2D])./e', 'strtoupper("##代码##")', strtolower(trim($match[1])));
if( isset($retVal[$match[1]]) ) {
$retVal[$match[1]] = array($retVal[$match[1]], $match[2]);
} else {
$retVal[$match[1]] = trim($match[2]);
}
}
}
//here is the header info parsed out
echo '<pre>';
print_r($retVal);
echo '</pre>';
//here is the redirect
if (isset($retVal['Location'])){
echo $retVal['Location'];
} else {
//keep in mind that if it is a direct link to the image the location header will be missing
echo $_GET[$urlKey];
}
curl_close($ch);

You may want to set the CURLOPT_FOLLOWLOCATION to true.
您可能希望将 CURLOPT_FOLLOWLOCATION 设置为 true。
Or set the CURLOPT_HEADER to true and then use regexp to get the Location header.
或者将 CURLOPT_HEADER 设置为 true，然后使用 regexp 获取 Location 标头。
